A COMPANY OF MAINE Application filed September sprmg of the type used on an automotive vehole.

The object of this invention is to mount a hicle in such a way that spring shackles will be unnecessary. More specifically it is an object of this invention to provide an effective mounting for a spring whereby one end of the spring may be rigidly connected to the chassis and the other end may be permitted limited longitudinal movement to compensate for bending of the spring. Such a structure is simpler and cheaper to manufacture than the usual spring shackle, and is more durable and less liable to break or become loose and cause rattling.

Other objects and advantages of the invention will appear in the course of the following description taken in connection with the accompanying drawing and appended claims.

In the drawing: Figure 1 is a side View of a spring suspended in accordance with my invention and st tached to the chassis bar of an automotive vehicle.

Figure 2 is an enlarged detail view of the rigid connection at the front end of the spring.

Figure 3 is a sectional view on the line 33 of Figure 1 showing in detail the resilient connection.

Referring to the drawing the numeral 10 denotes the longitudinal side member of the" chassis of an automotive vehicle and 12 and 14 the front and rear brackets respectively for suspending the ends 16 and 18 of the spring 15. The upper leaf of the spring at the end 16 is bent as at 20 around the project ing portion 22 of the bracket 12. The pro v rounded to allow for bending of the top leaf of the spring. Underlying the end 16 is a clamping plate 24,

jection 22 has its rear end 23 5 having a downwardly bent or curved end 26 also to allow for bending of the spring 15. The projecting portion 22, spring end 16 and clamping plate 24 have openings for the re ception of a bolt 27 having a nut 29 to hold Q It is to be noted that this spring on the chassis of an automotive Veextension 40' carry between SPRING SUSPENSION s, 1927.

' connection is rigid and holds the spi'ing end 16 immovable.

The opposite end 18 of the spring 1 5' hasa downwardly extending 100 36 'andis return bent as at 38 to overlap theend portion18. The bracket 14 has an" extension 40l which projects over the retumtent endf'38 and above and below the end 18 there are resilient blocks 42, preferably of rubber. Under the lower block 42 there is aelampifig'plat ie provided with a sunken portion placed the flanged metallic 'cup 'sliaped washer 46 which holds-the lower .partof t'he lower block 42 against undue displacement. The extension 40 of the bracket 14 is g f' oo v e'd fbr reception of'the reversely bent portion of theftopfle'af,o'f'thesp'ringl i "them the end "of the top leaf of the spring and the two blocks 4.2 and are heldtoge'therby side bolts .48; there on each side 'of'the bent being two sidejbol'ts I spring and. The heads and nuts 50 'o fthe four bolts are mended ontheir inner-on a djacen'tsides for fitting smoothly in similarly rounded seats 52 on theouter. sides of the plate 44 and extension 40 of the bracket -14. By. thisv arrangement the plate'44 isrperifiitted to swing'longitudinally but'reinains parallel to theexten'sion' 40.

As the spring bends the endfl1'8'mus't'move towardthe left," as shown Figure 1, since the other the T is rigidlyconn'ected to the frame. As the end 18 pullson'the rubber blocks and moves the plate 44 to the left the blocks are compressed and tend to return the spring to its'original positian."

I claim: 1 l "1. In" a spring suspension; aspring having one end in the general 'plane of the'Spi'ing and rigidly clamped; a resilient Suspension for the other end,*and an integral return bent portion'o'n said resiliently suspended end.

4. In a spring suspension, a spring having a resiliently suspended end, said resilient suspension comprising a bracket, a block of resilient material above and below said spring end, a plate below said lower block, a return bend on said spring, said return bend extending between said bracket and upper resilient block and means for holding said parts together. 5. In a spring suspension, a bracket overlying one end of the spring, a plate below the spring, means for rigidly securing the bracket, spring and plate together, a bracket at the opposite end of the spring, a return bent portion on said spring overlapping said second bracket, resilient blocks placed above and below said second mentioned spring end,

a plate below said lower block and means to secure said bracket, spring, blocks and plate together.

6. In a spring suspension, a frame member, a plate connected with said frame member for longitudinal surging movement, blocks of resilient material between said frame memher and plates, and a spring member having one end connected with the frame member, the other end extending between said blocks and connected to said frame members.

7 In a spring suspension, a spring having I a resilient connection at one end, said connection including a bracket attached to the chassis frame of a vehicle, a return bend on said end seated against said bracket, resilient means at opposite sides of said end, a plate below said end, and means to secure said plate to said bracket and confine the resilient means and spring end therebetween.

8. In a spring suspension, a resilient connection at one end ofsaid spring comprising resilient blocks above and below said end, a plate below said lower block, a bracket over said upper block, and means to secure said plate and bracket together but permitting limited movement of said plate relative to said bracket.

9. The structure of claim 8, said end having a return bent portion overlapping one of said blocks.

10. The structure of claim 8, said end having a return bent portion forming a loop, said return bent end overlapping the upper block.

11. The structure of claim 8, said means passing through said plate and bracket outside said spring end.
